This study intended to establish a novel machine learning model based on clinical data for predicting early re-currence of HCC after resection. Methods: A total of 220 HCC patients who underwent resection were enrolled. Clas-sification machine learning models were developed to predict HCC recurrence. The standard deviation, recall, and preci-sion of the model were used to assess the model's accura-cy and identify efficiency of the model. Results: Recurrent HCC developed in 89 (40.45%) patients at a median time of 14 months from primary resection. In principal compo-nent analysis, tumor size, tumor grade differentiation, por-tal vein tumor thrombus, alpha-fetoprotein, protein induced by vitamin K absence or antagonist-Ⅱ(PIVKA-II), aspartate aminotransferase, platelet count, white blood cell count, and HBsAg were positive prognostic factors of HCC recurrence and were included in the preoperative model. After compar-ing different machine learning methods, including logistic re-gression, decision tree, na?ve Bayes, deep neural networks, and k-nearest neighbor (K-NN), we choose the K-NN model as the optimal prediction model. The accuracy, recall, preci-sion of the K-NN model were 70.6%, 51.9%, 70.1%, respec-tively. The standard deviation was 0.020. Conclusions: The K-NN classification algorithm model performed better than the other classification models. Estimation of the recurrence rate of early HCC can help to allocate treatment, eventually achieving safe oncological outcomes.
